When is the best day to buy gas?

Wednesday

If you want to get cheaper gas, you should probably start heading to the pump earlier in the week.

According to new analysis by tech company GasBuddy, Monday and Tuesday are the best days to buy gas in most U.S. states because gas prices are generally lower at the beginning of the week.

According to GasBuddy’s previous studies, Monday has been the best day nationwide to buy gas for the past three years.

“Finally consumers have reason to be motivated about Monday since it offers the biggest savings on gasoline and little wait, if any, to fill up,” said Patrick DeHaan, head of petroleum analysis at GasBuddy. “As the week progresses and our excitement builds for the weekend, gas prices also have a tendency to rise."

The study concludes that Friday has the most expensive average price in most states. Friday is also the busiest time for gas stations nationwide, the study says.

“While filling up on a Sunday can save time, it doesn’t save money,” said DeHaan on the website. “Our data shows that filling up on a Monday morning each week can collectively save drivers $2.1 billion and avoid the possibility of playing bumper cars at the pumps.”

The website says prices were analysed using gas price data from the GasBuddy app from Jan. 1 to March 31, and wait times were calculated using anonymized and aggregated foot traffic data from the same timeframe.
